TRYGARN HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The two TRYGARN HOUSE sales from October 2010 and August 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the October 2010 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the August 2025 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might TRYGARN HOUSE be worth now?

TRYGARN HOUSE might now be worth an estimated £374,188.

This is based on house price inflation of 3.9%, between August 2025 and April 2026, for detached houses, in the Isle of Anglesey local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.9% inflationary increase is applied to the most recent sale price for TRYGARN HOUSE of £360,000 on 8th August 2025. For the value to have increased from £360,000 to £374,188 over the one year and four months to April 2026, the following assumptions must hold true:

• The value of TRYGARN HOUSE has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
